Enable each integration individually in the MCP for Blender sidebar panel inside Blender's 3D viewport. The AI reaches every library through search_assets and import_asset, and every generator through generate_3d. If an integration is switched off, the tool says so and tells the AI how to turn it on.
Enabling an Integration
Open the MCP for Blender panel
In Blender's 3D viewport, press N to open the sidebar, then click the MCP for Blender tab.
Check the integration you want
Find the integration checkbox (for example, Poly Haven, Sketchfab, or Poly Pizza) and enable it.
Enter credentials if required
For services that need an API key, paste the key into the corresponding field. Keys are saved persistently in Blender's addon preferences.
You can also set API keys via environment variables in the environment Blender is launched from (not in your MCP client config, since the Blender addon reads them): BLENDERMCP_SKETCHFAB_API_KEY, BLENDERMCP_POLYPIZZA_API_KEY, BLENDERMCP_HYPER3D_API_KEY, BLENDERMCP_HUNYUAN3D_SECRET_ID, BLENDERMCP_HUNYUAN3D_SECRET_KEY, BLENDERMCP_HUNYUAN3D_API_URL, and BLENDERMCP_MESHY_API_KEY.
